External Windows Selection in Hot-Summer and Cold-Winter Areas

Article Preview

Abstract:

Building energy conservation is a research hotspot at present. In this paper, using energy simulation software DesignBuilder, we analyzed the influence of different external window materials on energy consumption of residential buildings and finally studied the energy saving rate and economical efficiency. The economical efficiency was analyzed from two aspects: the difference of net present value and the pay back period. The result shows that Low-e insulating glazing is good at both energy-saving potential and economic benefits. This paper provides a basis for the external window selection in hot summer and cold winter areas like Wuhan.
